Definitions

  • the present invention relates to a method for lining pipes internally.
  • This process is applicable to industrial pipelines for corrosive products, oils, gases, crude oils, waste water, etc.
  • the old pipe remains in place and serves as an outer sheath for the tube introduced.
  • each operation cannot relate to lengths greater than 400 m.
  • such a liner cannot be carried out on small diameter pipes.
  • the aim of this new process is to produce a lining by minimizing as much as possible the loss of useful diameter, on the one hand, and by maximizing the lengths of lining by operation.
  • thermoplastic material with elastic memory is used to constitute the lining tube.
  • Such materials can be mechanically deformed at a temperature at least equal to the activation temperature of the memory and can be frozen in their deformed state by cooling. These materials tend to return to their original shape and dimensions when they are brought back to a temperature at least equal to the activation temperature of the memory.
  • crystalline polymers for example polyethylene; copolymers of ethylene with other ethylenically unsaturated monomers, such as copolymers of ethylene and vinyl acetate or ethylene and ethyl acrylate; ionomers such as a poly vinyl chloride, poly flu orure vinylidene, polytetrafluoroethylene or a copolymer of vinyl fluoride and hexafluoropropylene. These polymers are, of preferably cross-linked.
  • elastomeric materials e.g., crosslinked thermoplastic polyurethanes, nitrile rubber, copolymommed'éthylène and propylene and fluorinated elastomers, modified if necessary to allow them to resume their shape under the effect heat.
  • These materials can be crosslinked conventionally chemically or by high energy radiation.
  • the tube used in the present invention can be manufactured by extruding a suitable thermoplastic material and crosslinking the thermoplastic material after extrusion.
  • the extruded tube has a diameter at least equal to the inside diameter of the pipe to be lined. Its thickness can be small, that is to say it can go down to 3% or even less than the diameter of the pipe to be lined.
  • the tube thus obtained can be deformed when hot, then frozen in its deformed state by any appropriate means, for example by passing through a cold die, by rollers or even by vacuum.
  • Figs. 1A, 1B, 1C, 1D there is shown in Figs. 1A, 1B, 1C, 1D, four different shapes of tube sections 1 deformed, respectively crescent-shaped, H-shaped, star-shaped and U-shaped.
  • the star section can be obtained by rollers or passing through a cold die, as well as the H-shaped section.
  • the crescent and U-shaped sections can be obtained by vacuum and crushing, for example between two rollers .
  • Flattened H or U shapes are preferred because they have the advantage of being more easily wound on reels, while having a smaller footprint.
  • the tube thus deformed is threaded into the pipe to be lined. This can be achieved using a cable that was previously threaded using a piston.
  • FIG. 2 in cross section, a pipe 2 in which a deformed tube 1 having a flattened H shape has been threaded, as shown in FIG. 1B.
  • the deformed tube resumes its cylindrical shape and comes to press against the wall of the pipe, it is heated to a temperature at least equal to the activation temperature of the memory, in particular using a hot fluid that passing through the tube, for example hot water, steam or hot air.
  • a hot fluid for example hot water, steam or hot air.
  • FIG. 3 there is shown in FIG. 3, in cross section, the pipe 2 against which are applied the tube 1 after heating.
  • a cylindrical tube is made of high density, high molecular weight polyethylene crosslinked with silane by the Dow Corning process, having an external diameter of 102 mm and an internal diameter of 99 mm.
  • the material constituting the tube has a deformation or activation temperature of the elastic memory of 135 ° C.
  • This tube is heated to a temperature of 140 ° C. and it is deformed by passing it through a cold die to give it a flattened U shape.
  • a cable is introduced into the 1000 m long pipe, and the tube is pulled using the cable.
  • Water vapor under pressure at 140 ° C. is then sent to the memory tube.
  • the memory tube resumes its cylindrical shape and is applied against the wall of the pipe.
